Protections
Phase loss
protection
Input phase loss protection
Output phase loss protection
Overvoltage
protection
The AC drive stops when the DC voltage of the main circuit is
above 800 V.
Undervoltage
protection
The AC drive stops when the DC voltage of the main circuit is
below 350 V.
Overtemperature
protection
Protection is triggered when the inverter bridge gets
overheated.
Overload
protection
The AC drive stops after running at 150% of rated heavy-load
current for 60 seconds.
The AC drive stops after running at 110% of rated light-load
current for 60 seconds.
Overcurrent
protection
The AC drive stops when 2.5 times of rated heavy-load
current of the AC drive is exceeded.
Brake protection
Braking resistor short-circuit protection (unavailable for
models of 18.5 kW and below)
Short-circuit
protection
Output phase-to-phase short-circuit protection
Output phase-to-ground short-circuit protection
